Abstract
Abstract A carrying case includes first and second contact lens liquid storage chambers which are located on separate axes and have openings which are inverted one from the other. Each respective storage chamber has a plurality of threads for engagement with a compatible set of threads on each removable cap said caps being provided with a seal to promote integrity between the mating parts. Each cap has a convex base for receiving the concave surface of a contact lens and a concave cover pivotally supported to open and close immediately over the convex base to encapsulate the contact lens in the area defined between the convex base and the concave cover.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
122 words
A case for carrying contact lenses comprising: a. a body including first and second sides and at least one liquid storage means said sides facing in opposite directions, said liquid storage means having first and second openings, said openings being disposed about separate and spaced apart construction axes, said first opening being disposed on said first side, said second opening being disposed on said second side; b. first and second cap means, said first cap means cooperating with said first opening and said second cap means cooperating with said second opening to close said liquid storage means; and c. means for holding a pair of contact lenses, said means being supported on one of said liquid storage means and said cap means.
Claim 2
Dependent Claim
122 words
A case for carrying contact lenses comprising: a. a body including first and second sides and at least one liquid storage means said sides facing in opposite directions, said liquid storage means having first and second openings, said openings being disposed about separate and spaced apart construction axes, said first opening being disposed on said first side, said second opening being disposed on said second side; b. first and second cap means, said first cap means cooperating with said first opening and said second cap means cooperating with said second opening to close said liquid storage means; and c. means for holding a pair of contact lenses, said means being supported on one of said liquid storage means and said cap means.
Claim 3
Dependent Claim
42 words
The contact lenses carrying case as set forth in claim 1 wherein said liquid storage means comprises first and second separate liquid storage cavities, said first opening providing access to said first cavity, said second opening providing access to said second cavity.
Claim 4
Dependent Claim
21 words
The contact lens carrying case as set forth in claim 2, wherein said first and second sides are of stepped configuration.
Claim 5
Dependent Claim
52 words
The contact lens carrying case as set forth in claim 3, wherein said body portion includes first and second annular rings, said first annular ring being on said first side, said second annular ring being on said second side, said annular rings defining at least a portion of said liquid storage cavities.
Claim 6
Dependent Claim
33 words
The contact lens carrying case as set forth in claim 4, wherein said cap means are received over said annular rings and within the respective steps defined by said first and second sides.
Claim 7
Dependent Claim
69 words
The contact lens carrying case as set forth in claim 5, wherein the means for holding each of the pair of contact lenses includes a convex shaped lens support means provided on said one of said liquid storage means and said cap means and a cooperating cover having a concave shaped surface, said cover being pivotally engaged to said one of said liquid storage means and said cap means.
Claim 8
Independent Claim
198 words
A device for carrying contact lenses, comprising: a. a unit including first and second separate and spaced apart liquid storage means, said first storage means being inverted with respect to said second storage means, said storage means being disposed about separate construction axes; b. first and second removable caps, said first cap cooperating with said first liquid storage means to form a first closed cavity, said second cap cooperating with said second liquid means to form a second closed cavity, said caps having disposed on an interior surface thereof a convex shaped base for receiving the concave surface of the contact lens; and c. first and second covers each having a concave shaped surface, said first cover being pivotally engaged to said interior surface of said first cap adjacent said corresponding convex shaped base, said second cover being pivotally engaged to said interior surface of said second cap adjacent said corresponding convex shaped base, each of said covers being movable from an open position for placement of a contact lens upon said corresponding convex shaped base to a closed position for retention of said contact lens between said corresponding convex shaped base and said corresponding concave shaped surface.
Claim 9
Independent Claim
198 words
A device for carrying contact lenses, comprising: a. a unit including first and second separate and spaced apart liquid storage means, said first storage means being inverted with respect to said second storage means, said storage means being disposed about separate construction axes; b. first and second removable caps, said first cap cooperating with said first liquid storage means to form a first closed cavity, said second cap cooperating with said second liquid means to form a second closed cavity, said caps having disposed on an interior surface thereof a convex shaped base for receiving the concave surface of the contact lens; and c. first and second covers each having a concave shaped surface, said first cover being pivotally engaged to said interior surface of said first cap adjacent said corresponding convex shaped base, said second cover being pivotally engaged to said interior surface of said second cap adjacent said corresponding convex shaped base, each of said covers being movable from an open position for placement of a contact lens upon said corresponding convex shaped base to a closed position for retention of said contact lens between said corresponding convex shaped base and said corresponding concave shaped surface.
Claim 10
Dependent Claim
25 words
The device for carrying contact lenses as defined in claim 7, further including a raised annular ring disposed about each of said convex shaped bases.
Claim 11
Dependent Claim
37 words
The device for carrying contact lenses as described in claim 8, wherein each of said raised annular rings has a top surface contoured to provide easy access to a contact lens retained on said convex shaped base.
Claim 12
Dependent Claim
37 words
The device for carrying contact lenses as described in claim 7, wherein said convex shaped bases have reliefs defined therein, said reliefs providing channels for a liquid to directly contact the concave surface of a contact lens.
Claim 13
Dependent Claim
42 words
The device for carrying contact lenses as described in claim 7, wherein each of said concave shaped surfaces is defined by radially extending fingers, said fingers having spaces therebetween for a liquid to directly contact the convex surface of a contact lens.
Claim 14
Dependent Claim
28 words
The device for carrying contact lenses as described in claim 7, wherein said removable caps and said liquid storage means are provided with a plurality of complementing threads.
Claim 15
Dependent Claim
35 words
The device for carrying contact lenses as described in claim 7, further including a pair of seals and wherein each of said caps includes an annular recess for accepting one of said pair of seals.
Claim 16
Dependent Claim
48 words
The device for carrying contact lenses as described in claim 11, wherein a stop is provided on each of said removable caps to engage a stop surface defined by each of said liquid storage means thereby preventing said seals from being damaged by preventing overtightening of said caps.
